1. What is Surface to Volume Ratio of Double Point?

The Surface to Volume Ratio of Double Point is the numerical ratio of the total surface area of a Double Point to the volume of the Double Point. It provides important insights into the geometric properties and efficiency of this three-dimensional shape.

2. How Does the Calculator Work?

The calculator uses the Surface to Volume Ratio formula:

\[ RA/V = \frac{(2 \times h_{Cylinder}) + \sqrt{h_{First\ Cone}^2 + r^2} + \sqrt{h_{Second\ Cone}^2 + r^2}}{r \times (h_{Cylinder} + \frac{h_{First\ Cone}}{3} + \frac{h_{Second\ Cone}}{3})} \]

Where:

\( h_{Cylinder} \) — Cylindrical Height of Double Point (m)
\( h_{First\ Cone} \) — Height of First Cone of Double Point (m)
\( h_{Second\ Cone} \) — Height of Second Cone of Double Point (m)
\( r \) — Radius of Double Point (m)

Explanation: The formula calculates the ratio by considering the surface area contributions from the cylindrical portion and both conical portions, divided by the total volume of the Double Point shape.
